Unfortunately, the tuberculosis which is preventable and curable disease is still

one of the most serious health hazards in Korea. In 1970, the tuberculosis

prevalence rate in Korea was 4.2%, which meas 1.1 million tuberculosis patients

existed in Korea. However, the registered tuberculosis patients existed in Korea.

However, the registered tuberculosis cases were only 14.4% in 1973. It is said that

the large number of unregistered cases have been hidden in population without

knowing themselves having active tuberculosis. In the tuberculosis control program,

more effective and economic case finidngs have long been sought to solve the

problem.

This study was to test a hypothesis that T.B. skin test of preschool children

might identify the source of infection in the family under the assumption that the

preschool children are less active and their major activities are confined to

mostly with family members.

This hypothesis was tested in two ways; prospective and retrospective apporaches.

The data collected for the Second National Tuberculosis Prevalence survey by the

Ministry of Health and Social Affairs in collaboration with the Korea Tuberculosis

Assoication in 1970 were used for the test.

The prospective approach showed that the prevalence rate for tuberculosis

determined by X-ray finding among those who were family members of preschool

children whose skin test was positive was 5.1% and among those who were family

member of preschool children whose skin test was negative was 3.0%. Therefore, the

probability in finding of tuberculosis patients in the family with positive

preschool children was 1.7 times higher than in the family with negative preschool

children. And this was turned out to be statistically significant. This finding was

found out to be constant in urban and rural as well as by age distribution.

In retrospective approach, the skin test positive rates of preschool children

were 1.8 times higher among those whose family member had tuberculosis patients

than among those whose family member had no tuberculosis patients. This finding was

also constant in urban and rural.

In conclusion, the hypothesis was proved to be true in both prospective and

retrospective approaches. Therefore, it is suggested to do further study

particularly on the costbenefit analysis for the implementation of the method in

the field.
